Claims.

The invention relates to a dual combine and more especially to a harvester attachment for tractors.

The primary object of the invention is the 5 provision of an attachment of this character,

wherein a combine including two units is supported and operated at opposite sides of a tractor and each unit comprising a cylinder, concave, riddles, fan, grain auger and straw distributing conveyor, respectively, the two units being arranged at opposite sides of the tractor and extend from the front to the rear of the same, a single reel and a single sickle'being provided for both units and a divider is supported between the cylinders of the units for causing the grain cut in the direct path of the tractor to be directed into the cylinders when the tractor is advanced.

Another object of the invention is the provision of an attachment of thisoharacter, wherein each combine unit is provided with a shaft for operating its cylinder, concave, auger, fan and conveyor and one of these shafts is extended and connected tothe sickle so that these parts will be operated directly from the tractor, the engine thereof being the power unit.

A further object of the invention is'the provision of an attachment of this character, wherein the units providing the dual combine are readily' and easily mounted upon and operated by a tractor without requiring any change or alteration in' the makeup of the latter; v e

A still further object of the invention is the provision of an attachment of this character, which is comparatively simple in construction, thoroughly reliable and effective in its operation, readily and conveniently associated with a tractor and comparatively inexpensive to manufacture and install.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described illustrated in the accompanying drawings, which disclose the preferred embodiment of the invention and pointed out in the claims hereunto appended.

In the accompanying drawings:

Figure 1 is a top plan View of the attachment constructed in accordance with the invention shown applied to the tractor and partly in section.

Figure 2 is a sectional view on the line 2-2 of Figure 1.

Figure 3 is a fragmentary sectional view on the line 3-3 of Figure 1.

Figure 4 is a fragmentary sectional view on the line 4-4 of Figure .1.

Figure 5 is a fragmentary sectional view on the line 5--5 of Figure 2.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, A designates generally a tractor of standard construction and B each of the combine units associated therewith and constituting the attachment as Will be hereinafter fully described.

The tractor A as is usual comprises a chassis I0 which at the rear thereof has the rear drive wheels ll while at the front are the forward steering wheels I2, these being turned for the guiding of the tractor, the steering post I3 for said wheels l2 being operated through suitable steering mechanism M including a rearwardly directed steering shaft l5 having at its rear end a steering wheel l6 which is located conveniently for an operator when occupying the seat I! of the tractor. Supported on the chassis I0 is the internal combustion engine [8 which through suitable transmission and differential mechanisms (not shown) furnishes power to the rear wheels H of the tractor for the driving of the same.

Arranged at opposite sides of the chassis H] of the tractor are the combine units B each including a casing l9 having therein a thresher cylinder 20, a concave 2|, the cylinder beater 22, the grain pan 23, shoe sieves 24, the straw rack risers 25, associated troughs 23, the conveyor 21, the grain augers 28, the shoe fan 29 and the grain elevators 30 and 3!, respectively, the latter elevator 3| being in communication with a grain bin, trough or the like 32 while the elevator 30 functions as a tailings elevator and through the spout 33 delivers the tailings to the thresher cylinder as is usual.

These casings l9 at their rear ends are fixed in yokes 34 formed at the forward ends of arms 35 hinged at 36 to couplings 31 fixed to the rear axle housing 38 of the tractor so that the said casings I9 can swing vertically under adjustment thereof in a manner presently described.

The front upstanding supports 39 of the chassis ii] of the tractor for the steering post l3 have fixed theretoa cross head 49 formed with terminal guide ways 4| in which are slidably engaged guide loops 42 fixed to the inner vertical sides 43 of the casings l9. On the supports 39 above' the cross head are bearings 54 in which is journaled a crank shaft 45 havingthe cranks 46 pivoted at 41 to the sides 43 of the casings 19 so that on rotation of the shaft these casings will be raised and lowered. One of the cranks 46 has joined with it a throw arm 48 to which is pivoted a throw rod 49 also pivoted to a hand lever 50 carrying a' releasable latching device 7 coacting with a'keeper segment 52 suitably 7 cylinder and avoiding the passage of-the out material to the tractor centrallylocated between fixed to the tractor and thus by operation of the lever the casings l9 can be readily raised and lowered, this lever 50 being conveniently located for an operator of the tractor.

Arranged at the fronts of the casings l9 are the platforms 53 which are horizontally disposed and lead to the concaves 2| within these casings l9, 7 there being a divider 54 between these platforms:v

53 for directing cut material to each thresher the combines B while at the'forward edges of the platforms 53 and disposedcrosswise withrespect Z tovthe tractor A is asickle55, its cutter. bar. -'56 being'reciprocatedthrough a pitman 51 pivoted theretoland also'pivoted't'o' an eccentric 58' fixed to a driven shaft 59 which through'a'ge'ar con- '7 nection 60 in association with gearings 6i to the axles 62 'of the. cylinders 2flwill be operated. The gearings 6| are operated from shafts 63 having chain and sprocket connections 64 with theengine i8ofthe tractor, the said shafts '63 being equipped with the universal and slip-joints 65 and lilifrespectively, to avoid interference in the driven connections on'the raising and loweringof the combines B'which are raised and lowered in unison with each otheriwhen the lever 50 is actuated'and'inthis manner regulating the height of the sickle with respect to the material growing in afield. '7

Within each casing!!! and included as a part 'of each combine unit B is the usual straw conveyor Gland these conveyors 61 through the connection's 68 with'the shafts 63'will be driven while the other moving parts in the combine units will be operated from power furnishedby the' tr'actor inany suitable manner. a

1 Above the sickle '55 and the platform 53 isa reel 69 havingthe driven connections 10 with the axles 62 of the thresher cylinders 20, thecreel 69 being of conventional type. 11 ther'operation of thetractor as fast as the V grainis outfit falls upon the platform.53 and: is fed- :to the thresher cylinders 20; The grain 7 passes between the cylinders 20'andconcaves 2| Where the greater portion of separationtakes place and is then carriedon the conveyor to the grain pan. As. the grain pan; islvibrated, the grain flows down until it reaches theshoe sieves Where arblast of. air from the shoe fan carries away the chaff and thegrain falls through the sieves upon one of the chutes and runs down into its grain augerifThe threshed 'grain is carried by this grain auger into the lower end of the'grain elevator andelevated andadistributed over the recleaner sieves bythe secondgrain auger. Here it receives a-bla'stofcair from the recleaner fan.

The clean grainlfalls through the recleaner sieves and runs down into another grainauger which 7 carries itout into the. elevator 3| and disposes it in the bin' oil-trough 32,"the straw separated from the grain being. carried off by the straw conveyors 61 and disposed onto the ground. '2 V v The respective combine units 13 are of the usual wellfknowmconstruction excepting that the platformfic'a'nvas and lower elevator canvas. asis commonlin a harvester are eliminated. -What is claimedis: i
